Greater Manchester chooses Vivacity Labs to deploy AI-controlled road junctions to optimise traffic networks.

There has been a nation-wide boom in the number of cyclists since the Covid-19 pandemic took hold. With people avoiding public transport when getting around towns and cities, and the daily commute changing for many in the longer term, innovation in transportation is a pressing need across the UK.

To help address this, Vivacity Labs and Transport for Greater Manchester (TfGM) are rolling out award winning-AI-controlled ‘smart’ traffic junctions to accommodate the increase of active travel modes, such as cycling and walking, in the city during the pandemic.

Solution & Benefits

Vivacity Labs’ first-of-its-kind AI signal control system first went live early 2020, before scaling to simultaneously control three, neighbouring junctions in the Blackfriars area of Salford in September 2020.

Using sensors with inbuilt artificial intelligence, Vivacity enables TfGM to anonymously identify different types of road users at selected junctions and control traffic signals to allow different modes of transportation to be prioritised as and when required. With more cyclists on the road as people avoid public transport, these ‘smart junctions’ will be able to give priority to people on foot or bike where and when appropriate.

This initiative also has the potential to reduce emissions and improve air quality in the Greater Manchester area. Congestion and queuing can be reduced by traffic signals that respond better and more quickly to changes in traffic conditions than existing systems.

The project is part of a three-year Innovate UK co-funded programme alongside Immense Simulations to use AI to optimise traffic networks. Vivacity Labs has developed an algorithm that is able to adapt quickly to changing traffic conditions and efficiently implement high-level strategies at both local and city-wide scales.

 “Having already developed an innovative product in terms of their sensing technology, Vivacity has become well-versed in the relevant standards and have made impressive strides in the continuing development of their Smart Junctions system. We’ve been really impressed with how Vivacity has approached this, assessing current ways of working and addressing the complexities of managing a multi-modal transport network. Hopefully, this development will continue into something that will positively disrupt the industry and revolutionise active travel in urban areas.” Richard Dolphin, Highways Network Performance Manager, TfGM

“Smart traffic technology is just one of the many ground-breaking areas the government is funding to pioneer new ways for artificial intelligence and 5G to transform our lives for the better. We’re backing this initiative in (Greater) Manchester to improve the city’s transport, reduce journey times and cut pollution. I look forward to seeing its positive impact and sharing the lessons across the UK.” Digital Infrastructure Minister Matt Warman

The project has secured additional investment to expand throughout the trial region via the Department for Digital, Culture, Media, and Sport’s ‘5G Create fund’ which was announced in July 2020. The project will scale up to an area of 20 junctions in Manchester by the end of 2021 and aims to demonstrate impact in the real world in the form of improved journey quality for all road users in this region.

 Smart Junctions was winner of the Innovative Use of Technology award at the 2020 Intelligent Transport Systems, ITS(UK) Awards.
